I have now ordered a new USB connector board to see if that fixes it: http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=150713366355

Will report back.

---------- Post added at 06:30 PM ---------- Previous post was at 06:01 PM ----------

When did you buy your phones? This could be a problem on early batches.

Could you see what part number you have on the actual USB connector?

I see that on this replacement board the number is 1H13D, while my number is 1J10F.

Hey, strong work! You might diagnose this thing before Google does. Keep us posted.
[Samsung Galaxy Nexus] JSY00:
I'm experiencing this too, I did have it go away for about a week, but now it's back. I"m not looking forward to RMAing it, because I ordered it from the US and I'm in the Caribbean. I'm hoping the USB board replacement will work - waiting to see the results.

So glad I finally found this thread....

This started happening to me Friday night. First thing I noticed was while I was out the battery symbol had the lightning bolt in it as if it was charging, but it wasn't.

Long story short, nothing I do is able to charge the phone, both while the phone is on and while the phone is off) and it's REALLY pissing me off. The only response I can get from the phone is when it's off, it keeps looping over the two battery animations and acts like it's charging, but it's really not.

In all my playing around with it I somehow got it to charge to 40% yesterday. The only thing I can say for certain was that the phone was plugged in while I was trying to boot it up and when it shut off I didn't see the battery charging animations so I left it alone for a little bit before I checked it out and was surprised to see it charged a bit.

Today I was able to have it happen again and got the battery to 60%. This time I Started from the bootloader and again, when it turned off, I didn't see the battery animation.

I was able to reproduce this again just now by going into the bootloader and just choosing the option to power it off. Will report back in a little while to let you know if it charged past 60% after doing that.

Edit: powering off from the bootloader did not charge the phone. I accidentally pulled the battery and it went from 60% to 37% when I turned it back on. I think there is something screwy with my battery. Does anyone know if the regular Verizon battery fits in the GSM version?
[Samsung Galaxy Nexus] DaJMasta:
I've got at least a similar issue, but managed to get a fix working (at least for now). I've had the phone for about 2.5 hours now. I got it with around 50% charge, after 1.5 hours, it was at 24% so I went to charge it. Tried the included USB cable to my Windows 7 PC, it tried to install drivers, the install failed. The battery was labeled as still discharging and the unlock screen told me to charge the battery.

I proceeded to try the samsung charging head thing with the original cable in one outlet, then in two more - same result, no charging indicated. Tried with a brand new micro USB cable and had no results. Tried the other cable with the PC. I read around on the issue a bit and found this thread, since people were saying it could be software related, I figured I would power down the device and try again.

I powered down the phone while it was disconnected from USB. I then plugged it into the USB cable connected to my computer. My PC then recognized the device and installed the drivers correctly, the bolt over the battery icon appeared on the Galaxy Nexus's screen. I let the screen turn off then woke it again, the battery charging animation was going. I booted the device while connected to USB. Now in the OS it says the battery is charging and it was charging from about 42% - so I think the actual battery power was not being properly reported before the reboot and when the charging problems were happening.

I'm hoping this has set it to work, but if something else happens, I'll post here again.
[Samsung Galaxy Nexus] teleknEsis:
I've had the phone for over a month now and never had any issues. I've been trying to plug into a Mac so drivers aren't an issue (I know from previous phones that in Windows the phone wouldn't charge until the right drivers were installed).

There's definitely something very wrong w/ the phone and I fear it's likely a hardware issue, as even when the phone is off it won't charge (but acts kind of like it is).

Right now the only surefire way for me to charge my phone is let it die all the way down and keep trying to boot it up until it dies during a boot before the OS comes up (at which point it'll charge).
[Samsung Galaxy Nexus] teleknEsis:
For what it's worth I fixed the phone on Monday. I stuck a wooden stir stick from work in the usb port and pushed down on the plate inside ever so slightly. I'd seen this suggestion from a few places online, but I was pretty skeptical. Well, much to my surprise it started charging!

I quickly got it back to it's stock state and re-locked the booloader in case I end up needing to send the phone back to Sammy if the problem happens again.

So far so good, but I've been very careful when plugging and unplugging the usb cord.
[Samsung Galaxy Nexus] JSY00:
I think it's important to keep the OP's issue in mind, because I'm pretty sure there are two different issues here.

1)Many of us have an issue were the phone shows it's charging WHILE UNPLUGGED, causing the screen to flick on repeatedly. This may/may not be accompanied by a charging issues - in my case it isn't.

2)A second issue where owners have problems charging their phones (but never experience the charging while unplugged bug).

I think the intent of this thread is to track (1). I've never heard of the toothpick issue helping those experiencing (1).
[Samsung Galaxy Nexus] Skoogusmaximus:
How are people pushing the usb plate down, any pictures?
[Samsung Galaxy Nexus] MadMic:
I've just had the same issue yesterday - at first I thought it was a software issue and did the usual round of full wipes & flash to another RON.. eventually I blew the USB port out with a can of air duster and we're good to go again... my guess is either the port pins get corroded or the USB cable just doesn't make a good enough connection - I guess I'll have to wait and see if this sorts it, if not it's RMA time :(
[Samsung Galaxy Nexus] prozinecki:
Original charguers

YES! I strongly believe this is the problem

Got my GN back on december, always used the original charger and no problem. About one month ago i used my friend's BB car charger and I noticed that somehow the charger got stuck with the port when changing gears on the car, removed the charger and since then I started to have the problem

Looks like the only tru fix is to replace the charging port
[Samsung Galaxy Nexus] pgc1959:
Same problem since last week.

I've been having the same problem for about a week. My solution isn't a fix by any means but best solution I have found. Once battery is charged (needs unlocked boot loader) I just boot to recovery, reset permissions, reboot and problem gone until next time I charge the phone. Hopefully this will work for some and if so many someone with more programming experience can look into the permissions.
[Samsung Galaxy Nexus] totott:
Power out of usb port.

I really don't get this. Hardware/Software...

My usb post seem ok. But as many I have the lightningbolt on and off.

What is strange, is that the Nexus is sending electric current out from the usb port. I have a charger with a lightbulb on, and when it's connected to the Nexus, the bulb shines. Ergo, current is going out.

I am not sure if there is a connection between current out and lightningbolt issue, but it seems strange.

Any ideas?

[Samsung Galaxy Nexus] M_Shaaban:
Here is what worked with my Galaxy Ace and other people's Nexus.

Using a toothpick slightly pressing the male portion of micro usb up toward screen. While I am not suggesting anyone try it worked for me until Plugged in again.

Good luck!
[Samsung Galaxy Nexus] azeem.droid:
Aah got this problem since morning. Tried all the methods discussed above but in vain. Seems like i'll have to change the charging socket. Motorola i miss you. Samsung just cant keep their quality of products in check i guess. :banghead:
[Samsung Galaxy Nexus] kalo86:
Hi guys, I have the same problem: the battery bolt is present since 100% to 74% then the smartphone acts like standard mode (no issue).

I replaced the USB flex board with NO SUCCESS!

Maybe the problem is the battery?
[Samsung Galaxy Nexus] carpenter01:
I had the same problem and I decided to send my GNex back to my carrier since is still under warranty

so I locked the boot loader again and ever since then (3 days) I don't have any issues. Maybe somebody can try it to see if its working?
[Samsung Galaxy Nexus] kalo86:
Just made a little-fast test with another battery: no problem of battery because without any usb cable plugged the bolt is present....

I am not lucky!

My phone was with the stock 4.1.1, then I wanted to try to fix the issue with a custom rooted ROM, so I unlocked the bootloader and installed the new custom ROM with no success. I tried all things with no success!

I need to send my Nexus in warranty...
[Samsung Galaxy Nexus] azeem.droid:
Did any one replace the charging port strip. I think ill order it in a day or two. Hope it helps.
[Samsung Galaxy Nexus] kalo86:
I replaced the usb port and this did not solve the problem.

I don't advice to buy the new flex cable!
[Samsung Galaxy Nexus] animal24:
A broken battery would just not provide power, not charge itself. There is a chip in the phone (a TI twl6030) that handles power managment/charging. It seems yours has lost its mind. New phone would be the solution, not battery.

[Samsung Galaxy Nexus] kalo86:
Hi guys, I made a little test with another battery and the problem persists, then the problem is into another side, for example the chip described by animal24.

Usb flex cable is really cheap and can be replaced very fastly but the new motherboard has a huge cost...

Warranty!
[Samsung Galaxy Nexus] azeem.droid:
I removed the phone from the casing and after switching on the phone removed the usb connector and suddenly the charging indicator disappeared and everything started working normally. So came to the conclusion that usb charging port is at fault.
[Samsung Galaxy Nexus] tibibond:
Thank you so much for the great advice!! You helped me save some few bucks [ lei actually :))] god bless you!!!

My usb port got damaged after using a nokia charger . I also used a htc data cable, but i don t think that caused the damage; before going to any service you should think back if you used any other charger or accesories thet are not genuine. I will use only genuine samsung stuff from now on . Also a dust cover wont hurt for protecting the port from dust and moisture!!
[Samsung Galaxy Nexus] shokuchi:
I tried this and bingo it worked and has stayed "worked" for several days now and multiple charges. Previously I had the phantom charging icon, and sometimes the flicking from normal discharging to phantom charging and back again. I luckily had no trouble actually charging up my phone at anytime, If I plugged it in, it began charging properly, sometimes instantly, sometimes after 5-10 seconds. Sometimes it got confused between usb charging and AC charging. It was a befuddled phone. I had been using a huge variety of chargers and different cables to charge, I think one of them caused the issue, now I use the official cable only and the 5V 1.0A output plug. Just to be safe.

I also deleted viber - as it was causing 'android core apps' to drain the battery like crazy.

All is well...touch wood.

After I followed those steps I looked at the battery graph, there was a abrupt jump in battery level with a black line in the chart. Whatever I did I somehow reset the battery or something.

[Samsung Galaxy Nexus] mingkee:
My phone had the same problem. However, I found a fix by accident.

I am sure the problem caused by insufficient input voltage (USB). When the phone is off, charge the phone and observe.

If the battery icon flashes every few minutes, try different USB cable until the flashing of icon is gone. Once you found a "right" cable, go to CWM recovery and wipe the following:

battery stats

dalvik cache

cache

Reboot the phone and charge normally.

The problem should be fixed.
[Samsung Galaxy Nexus] najaboy:
You do realize that none of those steps in recovery aren't needed, right? They don't even remotely have anything to do with anything that could even remotely contribute to battery issues.
[Samsung Galaxy Nexus] JediNinjafication:
I beg to differ. I had this issue in may and thats only thing that worked. Then only use stock charger and no issues since. And the stats do too. This issue is caused in part from the nfc chip/antenna. If reading old stats not goung to charge proper is what i amounted it to.

*Shaolin Shadowboxing*
[Samsung Galaxy Nexus] najaboy:
Negative ghostrider. The notion that wiping battery stats has anything to do with charging or battery life is based on an outdated gross misunderstanding within the hobbyist community that has since been clearly and concisely debunked by an engineer from Google's Android team. The info being wiped is merely a list of the apps that have consumed power. The OS automatically wipes this file itself, making the misinformed advice to manually do so even more pointless than it already is.

Rather than believing misinformation derived from a Google search, which can easily lead one to subscribe to logical fallacies such as cum hoc ergo propter hoc, go straight to authoritative sources. The Android team regularly posts info via their individual Google+ accounts and Samsung, as well as other hardware manufacturers, has various whitepapers floating around that make for interesting reading.
[Samsung Galaxy Nexus] manoosie:
Having same issue. Phone keeps switching from charging to not every few seconds, which causes my screen to keep turning on and the battery icon to keep changing. Battery is getting drained fast. Tried wiping cache, reinstalling rom, etc. to no avail. How do I fix this?
[Samsung Galaxy Nexus] alf_malf:
a friend of mine had the same problem in past few days.

Problem seems to be in the usb port. Using non stock cables could be the origin of the damage. Using a little knife to move the internal part of the port fixed it.
[Samsung Galaxy Nexus] manoosie:
What do you guys do to the port? Just need some detail on what to do. Thanks.
[Samsung Galaxy Nexus] killbox:
Have the same issue. Sent it in for repair. All they did was "clean the usbport". That took 2 weeks. 2 days after I got it back the problem persisted. Don't want to send it back again and wait for it for another 2 weeks. I've had 6 HTC's in row without any problems, and this is my first Samsung... Not very promising Sammy...

hey before coming across your post i was planning to buy the flex cable,should i drop now:( then is there any solution to this super annoying problem,i dont even have warranty cause i got it shipped from a country different from where i live.help me
[Samsung Galaxy Nexus] PhoenixBlitz:
I'm having some pretty annoying problems too. Sometimes my phone wants to charge and sometimes it doesn't. What happening recently is that it will fully charge, then I go to bed and I wake up in the morning and it says Charging 72%. Which gets really annoying, and now it won't charge at all . It says charging on the lockscreen and shows the charging bolt in the top right but it just won't charge. Could this be the battery or the charging port?
[Samsung Galaxy Nexus] zinnet:
sorry
[Samsung Galaxy Nexus] 7tosta:
It's probably a software problem. Try updating your Android version.
[Samsung Galaxy Nexus] wisepage:
I've started having this problem too, not long after applying a skin to my phone. I'm concerned that in that process, some moisture entered the micro USB port.

I tried cleaning out the port with isopropyl, drying it with a hair dryer, bending the male tab/tongue back to a central location using a knife, did a full discharge/recharge cycle as well as wiping cache/dalvik/battery stats. The problem seemed to be gone for the first few charging attempts,but returned shortly after.

The phone seems to charge OK, but pretty much always thinks it is on charge when it isn't. This seems to cause rapid battery discharge, even though the screen isn't waking up. Just ran a test and the phone discharged from 93% to 89% in 20 minutes, even though the screen never turned on!

** Interesting side note **

Despite the fact that the phone almost always thinks it is on charge (the lightning bolt symbol appears in the notification bar, and the lock screen says "charging"), one thing that does seem to be working correctly is the "battery bar" which comes with my ROM (Codename Android 3.2) doesn't seem to be fooled. The battery bar is a little 1 pixel wide blue line which indicates the remaining battery %. When the phone is charging, an animation occurs where a small dot flies across the screen and into the battery bar, to symbolise charging. When the phone is "phantom charging" (lightning bolt icon, lockscreen charging indicator), the battery bar does not display this animation! When I plug it in, the animation begins. So the battery bar knows that charging isn't occurring but the rest of the OS does not. Not sure if this is important or not, but thought it was worth mentioning.
[Samsung Galaxy Nexus] BlackJou:
Got the same problem, any ideas?
[Samsung Galaxy Nexus] kalo86:
The solution is only one: replace the motherboard.

I am having my Nexus always in warranty for repair: until now I had a replacement of the USB flex cable (again from the Samsung warranty) with no success, then the USB port replacement and the battery replacement with again no success.

The Samsung assistance is very bad. They don't want to replace the motherboard and I don't know the main reason.

Soon I will update the result... I'm very tired.

[Samsung Galaxy Nexus] samir_madan:
Dear all....have came across this link - http://xdaforums.com/showthread.php?t=1578469 in XDA itself which says that G2X Cable can do magic for your phone...did anybody tried it? If so, then do leave a feedback so that the rest of us can be relived....
[Samsung Galaxy Nexus] noojster:
Hi fellow Gnex users,

I also had the same issue and read a lot of tweaks, techniques, and workarounds not only here in xda but also in other sites.

and this is confirmed a hardware problem in the usb port, not software related.Trust me, Ive flashed a lot of ROMS like hell and it still happens.

But this worked for me.. Im not having the issue for a week now. Crossing my fingers it wont happen again.

Before I begin saying the solution, I noticed this problem started when I began using my Nexus 7 usb cable as my main charger both for my Gnex and Nex7, since it was convenient for me.

I already forgot who or where I read the statement, but I guess this user was also using a different cable rather than THE ORIGINAL CABLE PROVIDED FOR THE GALAXY NEXUS, and he/she managed to heal the problem over time by religiously using the official cable. I didnt believe it at first but when I double checked with my own eyes, the usb connector's "teeth" is slightly different from other cables, which is the reason why the official cable fits fully into my Gnex and the Nex7 cable was not fitting fully although it also works. Didnt notice it before but I think it damaged it a bit.

Here's what I did.

I used an office pin,

and pushed the tongue of the Gnex's usb port very lightly and slightly upward(towards glass) so it no longer touches the base which I believe is the cause of using a different cable. While doing this, I noticed my Gnex doing the phantom charge once again. After this I gently blew inside the port for any dust and used a toothpick with a small cloth dipped very lightly on isopropyl alcohol to gently clean it for any dust, Please take note to do this VERY GENTLY and make sure the cloth isnt fully wet by the alcohol, but enough to make the dust sink in the cloth. Fully check the bottom of the tongue if there is absolutely no point of contact within the base even dust.

After this, the problem still persists.. and I am forced to reinsert the battery and be lucky to have it charged truly when I needed it to be charged.

but in these days I used the official cable provided, the problem was slowly going away, and right now I have recorded that its been a week that absolutely no problem happened. It was charging normally, it was detected by usb charging and media connection as well and the phantom charge never happened. During sleep I only lose a few percentages which was normal.

I hope this helps to others, I am not technically speaking that my methods above will surely cure the issue but it worked for me. Hope it doesnt happen again.

PLEASE USE THE OFFICIAL CABLE PROVIDED BEFORE IT GETS TOO LATE!

Regards,

noojster
